AWS Certified Solutions Architect – Associate (SAA-C02) — Question 573

A solutions architect is investigating AWS file storage solutions that can be used with a company's on-premises Linux servers and applications. The company has an existing VPN connection set up between the company's VPC and its on-premises network.
Which AWS services should the solutions architect use? (Choose two.)

Answer options

• A. AWS Backup
• B. AWS DataSync
• C. AWS Snowball Edge
• D. AWS Storage Gateway
• E. Amazon Elastic File System (Amazon EFS)

Correct answer: D, E

Explanation

Amazon EFS supports mounting on-premises Linux servers over a VPN connection using the standard NFSv4 protocol, providing a fully managed, elastic file system. AWS Storage Gateway (specifically File Gateway) enables on-premises applications to seamlessly access file storage in the AWS cloud with local caching over NFS. Other options like AWS Backup, DataSync, and Snowball Edge are designed for data protection, transfer, and physical migration rather than serving as active, network-attached file systems.
